IX/37 XMM-Newton Serendipitous Source Catalogue (1XMM) (XMM-SSC, 2003)
The XMM-Newton Serendipitous Source Catalogue, Version 1.0.1
XMM-Newton Survey Science Centre Consortium
<XMM-SSC, Leicester, UK (2003)>
ADC_Keywords: X-ray sources ; Surveys ;
Mission_Name: XMM
Description:
1XMM is the first comprehensive catalogue of serendipitous X-ray
sources from the European Space Agency's (ESA) XMM-Newton observatory
launched in December 1999, and has been constructed by the XMM-Newton
Survey Science Centre (SSC) on behalf of ESA. Most (>80%) of the
entries have not previously been reported as X-ray sources.
The catalogue contains source detections drawn from 585 XMM-Newton
EPIC observations made between 2000 March 1 and 2002 May 5; all
datasets were publicly available by 2003 January 31 but not all public
observations are included in this catalogue. Net exposure times in
these observations range from less than 1000 up to about 100000
seconds. The total area of the catalogue fields is about 90deg2, but
taking account of the substantial overlaps between observations, the
net sky area covered independently is about 50deg2. The observations
sample, albeit sparsely, most of the sky, with the exception of a
'hole' centered in the Cygnus region, caused by spacecraft observing
constraints.
The catalogue source detection and parametrization technique is
optimized for point-like sources, and has been performed across
several photon-energy bands (see "EPIC energy bands" below) and using
data from each of the three EPIC cameras PN, MOS-1, MOS-2; the
prefixes PN_ M1_ M2_ are generally used to designate the columns of
the catalogue related to the detections by the corresponding camera.
The catalogue in its FITS version has ∼ 400 columns; these include
source-detection parameters (likelihood, position coordinates, counts,
count rate, flux, hardness ratio, background estimates, errors etc),
the results of cross-correlation with a large number of archival
catalogues (SIMBAD, NED, USNO, GSC, APM, ROSAT etc), quality 'flags'
resulting from visual screening, and 'meta-data' relating to the
observation. For practical considerations the ascii version of the
catalogue is made of 3 tables representing the sources, the
observations and processing details, and the results of the
cross-correlations; the names used as column names in the ASCII
version are also reported within parentheses in the "Byte-by-Byte"
descriptions below.
Details about the construction of the catalogue can be found from the
XMM-Newton Survey Science Centre (http://xmmssc-www.star.le.ac.uk/)
EPIC energy bands:
Narrow energy bands:
1 = 0.2 - 0.5 keV
2 = 0.5 - 2.0 keV
3 = 2.0 - 4.5 keV
4 = 4.5 - 7.5 keV
5 = 7.5 - 12.0 keV
Broad energy bands:
6 = 0.2 - 2.0 keV = soft band, no images made
7 = 2.0 - 12.0 keV = hard band, no images made
8 = 0.2 - 12.0 keV = total band
9 = 0.5 - 4.5 keV = XID band

--------------------------------------------------------------------------------
Note (1):
The total band flux (0.2-12keV) of the detections by the concerned
camera (PN, M1, M2), and the mean flux (column Flux) weighted by the
errors, all expressed in erg/cm2/s. A camera detection is only
included in the calculation of the mean if the flags #1 (false
detection), #5 (suspect position), and #6 (near-edge source) are all
set to False (0) for this camera. This can lead to the situation where
Flux is set to NULL for a valid source because none of the camera
detections satisfy these criteria. It is to be treated as an upper
limit if the source was not detected but observed with any one camera.
Note (2):
Value of the background map at the location of the detection by the
concerned camera in counts per image pixel (the image pixel size is
4arcseconds).
Note (3):
Off-axis angle of the detection by the concerned camera (PN, M1, M2)
in arcminutes, that is, the tangential radius from the nominal center
of the focal plane (which is also the origin of the CAMCOORD2 system).
Note (4):
Total band source counts (0.2-12keV) of the detection by the concerned
camera (PN, M1, M2) under the total PSF (point spread function) and
corrected for background.
Note (5):
The detection position by the concerned camera (PN, M1, M2) is made of
the CCD number, and the CCD-specific raw (x,y) pixel positions.
Note (6): Distance to the nearest neighbour for the same exposure,
on the concerned camera (PN, M1, M2)
Note (7): Likelihood of the statistical fit to the cross-correlation of
source matches of detections of this XMM observation with USNO-A2.0
coordinates. If the fit is reliable (posOK=1), the resultant
correction is used to rectify the RA and Dec coordinates from the
observation source lists (cols RAobs and DEobs) into corrected
coordinates (cols RAdeg and DEdeg).
Note (8):
The likelihood values are computed from a simultaneous PSF fit to the
source count distribution in each energy band. Note that likelihood
values are related to the probability p of a detection occurring by
chance by L=-ln(p). The expected number of spurious detections as a
function of likelihood has been estimated by simulation to be about
10, 5, 2, 1 per EPIC exposure (i.e., for a single camera) at
likelihood thresholds of 6, 8, 10, 12.
Note (9):
The hardness ratios are defined by:
HR1 = (bd2-bd1)/(bd1+bd2) : [0.2-0.5keV] vs [0.5-2.0keV]
HR2 = (bd3-bd2)/(bd2+bd3) : [0.5-2.0keV] vs [2.0-4.5keV]
HR3 = (bd4-bd3)/(bd3+bd4) : [2.0-4.5keV] vs [4.5-7.5keV]
The values are between -1 (softest) and +1 (hardest).
Note (10): 12 verification flags are possible.
The first 7 have been assigned the following meanings:
1 false detection
2 no visual inspection
3 the source lies within an extended region
4 there are nearby sources
5 the source position is suspect
6 the source is near an edge (of a CCD and/or the field-of-view)
7 a source comment is given
The individual values of flags 1, 3, 5, 6 and 7 are reported in
dedicated columns, with a value of 1 when the flag is set. The 12
flags are also reported as flag strings, with 'T' (true) indicating
that a flag was set, and 'F' (false) a non-set flag; a dash (-) is
used when the source was not observed or detected.
A comment exists when the flag #7 is set.
Note (11):
The vignetting factor represents the fraction of the value of the
exposure map at the position of the detection as compared to the value
at the nominal point where the optical axis of the telescope in front
of the camera intersects with the focal plane.
For details see the 1XMM User Guide.
Note (12):
For each camera (PN, M1, M2) and each energy band, are given the
encircled energy fraction (EEF) of the PSF within the cut radius
of the subimage used for the PSF fitting.
In this version the cut radiuses are identical in all energy bands.
